saw my doc today and he said everythings fine and there is nothing to worry about. He also told me that my uterus is tilted downward so that was most likely the cause for pain and that my husband just needs to be a little more gentle. We also got to see the baby today via ultrasound and it jumped around while we were watching so that was very exciting.
I think you need to speak to your doctor and once they check you out ask the doctor point blank why sex hurts you.
Sometimes it's just the extra bloodflow to the cervix, other times it can be that your just too tender/swollen in there. it happens. GOOD LUCK
